I also got some push back here in Northern NJ. I am not ready to buy yet mainly b/c I haven't even test driven the car. Obviously dealerships are looking for quick sale and want to move their inventory but hopefully you will find a good honest dealer who can order what YOU want when you want it at a reasonable price (which imho is around invoice).
I second that comment about joy riding. When I special orderd my Vette a number of years ago, the salesman must have drove the $hit out of the car b/c it had 20+ miles at the time of delivery and I had to deal with nasty rear diff whine because of improper break-in straight from the time car went into PDI. As noted earlier, I am not taking delivery unless the car has under 10 miles
